The present invention relates to a complex valve, and, more specifically, to a complex valve which is capable of simultaneously obtaining an improved sealing property and a property for easily switching by integrating a bellows valve and a ball valve into one valve, wherein the sealing property is obtained by the bellows valve and the property for easily switching is obtained by the ball valve. For realizing the complex valve, the present invention is capable of integrating the bellows valve and the ball valve into one valve so that the up/down motion of the bellows valve is converted into the horizontal rotation of the ball valve. In particular, the present invention allows structural variations in a normal bellows valve and ball valve to be minimized when the bellows valve and the ball valve are integrated into one valve, thereby easily replacing an existing installed valve, and easily manufacturing and maintaining the complex valve according to the present invention. Therefore, not only the durability and competitiveness of the complex valve according to the present invention is improved, but also the stabilities of various fluid lines and systems using the complex valve of the present invention are improved. |
